Waitakere City is best seen by car. Although buses and trains do service the area, many are slow and serve those living in the suburbs as opposed to those looking to see the sights. Information on public transport can be found at MAXX (http://www.maxx.co.nz) Auckland Regional Transport, it allows you to select bus, train or ferry and so help to plan an itinerary.
A Surf Shuttle (http://www.surfshuttle.co.nz/) offers transportation via mini-bus to Piha Beach and around the surrounding wineries and beaches.
